电子战中基于互信息准则的双鲁棒波形设计

电子战环境中，针对雷达和干扰机的性能会因为对战场博弈环境的不了解以及频谱信息的不精确估计而受到影响，研究了雷达发射波形和干扰波形的能量分配问题，雷达和干扰机在对抗过程中可以通过优化自身发射波形获得更好的性能。在现实中，由于雷达无法获得精准的目标频谱和干扰频谱，并且干扰机也无法获得精准的目标频谱和雷达发射信号频谱，分别以雷达和干扰机为领导者，建立层次博弈模型，提出一种双鲁棒波形设计方法，该方法以互信息为准则，在能量约束下建立双鲁棒发射波形的优化模型，利用拉格朗日乘子法分别求解双鲁棒雷达发射波形和双鲁棒干扰波形。仿真结果表明，在最坏情况下，该方法可以提高雷达参数估计性能和干扰机性能。

ouble robust waveform design based on MI criterion in electronic warfare

In the electronic warfare environment, the performance of radar and jammer will be affected by the lack of understanding of the battlefield game environment and the inaccurate estimation of spectrum information. This paper studied the energy allocation problem of radar transmission waveform and jamming waveform, and radar and jammer can obtain better performance by optimizing their own transmission waveform in the process of confrontation. In reality, because the radar cannot obtain accurate target spectrum and jamming spectrum, and the jammer cannot obtain accurate target spectrum and radar transmitted signal spectrum, the radar and jammer are taken as leaders respectively, a hierarchical game model is established, and a double robust waveform design method is proposed. The optimization model of dual robust transmit waveform is established under the energy constraint, and the dual robust radar transmit waveform and dual robust jamming waveform are solved by Lagrange multiplier method. Simulation results show that the proposed method can improve the radar parameter estimation performance and jammer performance in the worst case.
